[0020] ​The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a kind of mobile round vibration screen mechanism, including the mounting plate 10 of roller, through the design of roller, equipment can conveniently move in different terrain, improve work efficiency.

[0022] The top of the fixed base 11 of the mounting plate 10 is provided with a screen box 13 installed by a spring 12, and the inner cavity of the screen box 13 is sequentially provided with screen meshes 14 with different hole diameters from top to bottom. The bottom of the screen box 13 is fixedly provided with a wind conveying pipe 131 extending into the inner cavity of a box body 15. The side surface of the box body 15 is communicated with a fan 16 through an air inlet pipe 151. The air inlet pipe 151 is embedded with a filter screen 152. During operation, the fan 16 discharges the gas in the upper chamber of the box body 15 through the air inlet pipe 151, so as to form a negative pressure in the upper chamber. The negative pressure is transmitted to the inside of the screen box 13 through the wind conveying pipe 131. When the screen box 13 performs screening operation, a downward suction force is generated. The suction force can effectively reduce the adhesion of materials on the surface of the screen mesh 14, prevent the materials from blocking the screen mesh 14, and ensure that the surface of the screen mesh 14 maintains high cleanliness. This mechanism improves the screening efficiency and screening accuracy. At the same time, the impurities in the air are filtered through the filter screen 152, so as to prevent the impurities from entering the inside of the fan 16, thereby avoiding the damage of the fan 16.

[0023] The bottom wall of the lower chamber of the box body 15 is rotatably provided with a reciprocating rod 20 provided with two strip-shaped holes. The side of the reciprocating rod 20 away from the rotation center is provided with a groove for driving a cleaning rod 17. The cleaning rod 17 penetrates into the upper chamber and is used for cleaning the filter screen 152. The rotating end of a rotating motor 21 installed on the top wall of the lower chamber is fixedly provided with a rotating disc 22. The driving column 221 of the rotating disc 22 extends into the strip-shaped hole away from the rotation center. The bottom of the box body 15 is provided with a sector-shaped hole. The bottom of the screen box 13 is slidably provided with a moving rod 23. The moving rod 23 penetrates through the sector-shaped hole and extends into the other strip-shaped hole.

[0024] In the working process, the rotary motor 21 drives the rotating disc 22 to rotate, and the rotating disc 22 drives the reciprocating rod 20 to produce a fan-shaped reciprocating motion through the driving column 221 deviating from the center of the surface of the rotating disc 22, and the reciprocating rod 20 in turn drives the cleaning rod 17 to produce a linear reciprocating motion, and the cleaning rod 17 cleans the filter screen 152 to prevent the filter screen 152 from being blocked, thereby ensuring the normal operation of the fan 16, effectively avoiding equipment failure caused by blockage, significantly reducing the frequency of equipment maintenance, prolonging the service life of the equipment, and improving the overall reliability of the equipment.

[0025] Meanwhile, the reciprocating rod 20 drives the moving rod 23 to swing in the rotating process, and drives the sieve box 13 to vibrate through the moving rod 23, thereby realizing the screening of the material. The moving rod 23 can slide along the strip-shaped hole. When the reciprocating rod 20 rotates in a fan-shaped reciprocating motion, there is a difference between the rotation range close to the rotation center and the rotation range away from the rotation center. When close to the rotation center, the vibration amplitude is smaller, and when away from the rotation center, the vibration amplitude is larger. This design can flexibly adjust the vibration amplitude according to the particle size requirements of different materials, thereby effectively improving the accuracy and screening effect of the material screening.

[0026] Further, the upper cover 18 is installed on the top of the sieve box 13, the upper cover 18 is provided with a feeding pipe 181 on the top, and the sidewall of the sieve box 13 is provided with a plurality of discharge pipes 132.

[0027] Further, the sieve screen 14 is fixedly connected with the inner cavity wall of the sieve box 13 through the screen frame 141, and the sieve screen 14 is placed in order from large to small and small aperture from top to bottom.

[0028] Further, the box body 15 is arranged in the inner cavity of the base 11, and the bottom of the box body 15 is fixedly connected with the top of the mounting plate 10.

[0029] Further, the inner cavity wall of the box body 15 is provided with a sliding hole for the cleaning rod 17 to penetrate, the sliding hole is in a strip shape, and is used for limiting the linear reciprocating motion of the cleaning rod 17. The cleaning rod 17 is driven by the reciprocating rod 20 to realize linear reciprocating motion, and can remove impurities on the filter screen 152. This self-cleaning function significantly reduces the frequency of manual intervention, improves the automation level and working efficiency of the equipment, reduces the operation cost, and makes the equipment more suitable for long-time continuous operation.

[0030] The outer wall of the air conveying pipe 131 is fixedly connected with the flexible sealing ring 19 fixedly connected with the inner cavity wall of the box body 15, and the sieve box 13 and the box body 15 are sealed by the flexible sealing ring 19, which ensures the sealing performance of the box body 15, effectively prevents the leakage of airflow in the working process, and at the same time, the flexible sealing ring 19 can adaptively move with the vibration of the sieve box 13, without affecting the overall operation efficiency of the equipment. This design ensures the stability and sealing performance of the equipment in long-term operation.

[0031] Further, the screen box 13 is of sectional design, capable of single-layer or multi-layer combined installation and use, the screen box 13 is of sectional design, capable of single-layer or multi-layer screen mesh 14 combined use according to needs, users can select appropriate screen mesh 14 combination according to the screening requirements of materials, further improve the applicability and flexibility of the equipment, the sectional design also makes the installation and disassembly of the equipment more convenient, facilitating the rapid deployment and adjustment in different operation occasions.

[0032] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
